I suspect most of us have. The VERP feature means that messages
*have* to be sent separately. But I still can't see why it
can't send multiple messages down a single connection instead of
attempting to flood MXs with multiple connections. Not that I care.
Setting:

smtp_accept_max_per_host = 5

on our MXs (same value as Chris uses) means I don't have to care.
